CDAP namespaces can now be mapped to custom namespaces in storage providers. While creating a namespace, users can specify the Filesystem directory, HBase namespace and Hive database for that namespace. These settings cannot be changed once the namespace has been created successfully.

Description

Currently, when an user creates a namespace CDAP handles creation/deletion of namespaces in underlying storage systems (hbase, hdfs, hive) with a specific name. This is useful because it allows user not to worry about namespace management in the underlying storage.

Although, in some cases a user might want to map cdap namespace to a custom namespace in underlying storage system for better control. For example, an user might want control the naming of underlying namespaces or does not want cdap to create namespaces in underlying storage on its own and just allow cdap to access some namespaces for security reason.
